FTP adapter

Hi community,

I am now working with an ftp adapter. I have no problem connecting to the FTP server, but there are problems with interacting with files. Has anyone had any experience with an FTP adapter, such as getting/modifying/deleting files?

Dear All,

I’m having trouble creating the following business service. It’s intention is to pick up an CSV via FTP and pass it to a Business process that transforms it to a HL7 message.

I have created a record map for the CSV file, which I am trying to call in the business service and parse it into a new message class, which can be transformed in the business process.

Please could you advise:

Explicit FTPS in Cache

We use the %Net.FtpSession class to perform FTPS file transfers. This has worked fine with Implcit FTPS servers but crashes when trying to connect to an Explicit FTPS server. Explicit FTPS has a slightly diffferent negotiation in the intitial connection and different ports.

Has anyone gotten Explicit FTPS working with the Cache classes?

Hi All,

i have a issue in getting the complete file path when using the FTP Adapter in service.
EnsLib.FTP.PassthroughService / EnsLib.FTP.InboundAdapter

I need to know the folder name (including sub folder) where the new file is found by the service when looking up for new files.
The normal file class is working good as expected

More details below,

In the below two examples you can notice folder name is fetched by normal File adapter, but in FTP only the file name is available.

I have been using %Net.FtpSession and while it works, its handling of file/directory listings from an FTP server is less than ideal and, while this is due to the FTP protocol itself, the class could be written to handle this as would an FTP client such as FileZilla and command line/class FTP handlers for other languages. I was wondering if anyone knows how the Ensemble adaptor works with this in case it provides code that would help, though the source does not seem to be available. Below are the issues I see in FTP, some are based on past experience writing our own FTP handler in the past

Morning everyone,

I would appreciate some advice please- hopefully there is plenty of experts out there.

We are setting up an sFTP share between hospital trusts here in the UK and I have set the outbound operation up using a custom extension of EnsLib.HL7.Operation.FTPOperation.

We are configuring a VPN tunnel to run between the sites also so there is a bit of firewall / network routing to take place to enable the connection but to add in a complication we are on a mirrored cluster and usually present on a Virtual IP address.

Dear Community,

I need to collect a file from an FTP server over FTPS.

I have the :

  • credentials saved correctly
  • correct host and port informatoin
  • correct filepath I am trying to collect from
  • I have setup the SSL configuration in System > Security Management > SSL/TLS Configurations and this tests sucessfully

When I run the business service to connect it connects, but soon after connecting it fails to open the directory:

Looking for some suggestion on what the community has been setting Confirm Complete to? The testing I did when this was set to size is way too slow at around 1 message for 2 seconds. Is it safe to set this value to None? Would I get half messages if the sending system didn't compete writing the message.

Hello!

I'm currently trying to setup a SFTP Ensemble production to handle all of my SFTP transactions. It's been going well, but I'm currently running into an issue where it is saying it is unable to exchange encryption keys. Error Below:

Unable to exchange encryption keys [80101005] at Session.cpp:238,0' matched ReplyCodeAction 1 : 'E=R' resulting in Action code R

Any advice on getting around this would be appreciated.

We have a custom FTP Service , and custom FTP adapter . Customization is just to find a duplicate file and for giving specific dynamic file spec pattern.
While running and polling for files, we are getting this error. Could you please help ? What's the issue and how to resolve it ?

Hello,

I have a EnsLib.HL7.Operation.FTPOperation that uses SFTP protocol and public/private key to connect to an external vendor moveitcloud.

Issue: The vendor is planning to enable Multi Factor Authentication for this file transfer account.

Question: Have you configured a SFTP operation to use Multi factor Authentication? If not, is there another way?

Thank you,

Creating an FTP Report

Good morning all,

A question to see if anyone out there is already doing this.

We have built a custom BS based off of the EnsLib.FTP.InboundAdapter. We have our processes wake up (using the Scheduler), grab the files in the directory, stay awake for a while, and then go back to sleep.

Each file goes through on its own message. So we can trace each individual file and we know if it made it successfully or not.

I'm designing a workflow for PHR via FTP. What I've done is create a single FTP adapter to pick up files from multiple customers. A router then accesses a lookup table and determines if a particular customer is allowed to send a particular message type to the state. If not, the message doesn't go out. It seems like everyone is against this approach (other than my CEO, thankfully), including Intersystems:

SFTP connection problem

Hello,

I have been facing a problem for several months, I have several flows that work in SFTP with the iris class EnsLib.FTP.PassthroughService

The problem is that from time to time I get an error message that says:

"A connection could not be established because the target computer expressly refused it"

I had the case for a server at our house and we solved the problem by extending the call interval parameter to 60 seconds,

Hello,

I am trying to send a HL7 Billing Batch 2.3:FHS file out to an FTP site:

The file needs to be in Variable Length / Carriage return carriage control format--

When I send the file, the format is Fixed Length 512 Byte Record-- Not Working

The data is ok within the file-- It is just the way I am sending it out of Ensemble that is not correct.

I am thinking that it is a setting within the Operation that I am missing or not choosing correctly.

In 2020 we implemented HealthConnect as our HL7 interface engine. Having completed this, we are currently evaluating whether it would be beneficial to migrate our managed file transfers from our current MFT software, MOVEit to HealthConnect. I am interested in hearing from any InterSystems customers who have previously used MOVEit and currently using HealthConnect for file transfer managment. Any feedback would be appreciated.

Logging FTP Business Service

I am having an issue with a file not being deleted from the FTP server and returning an error to this effect. The file, however, was fully processed. This causes the file to process again.

My question is I seem to recall a flag that can be set to enable more detailed tracing to be done on the FTP service/adapter. However, I have not been able to locate this. Does anyone recall such a logging setting or was I just dreaming?
